👉 IgDna, also known as immunoglobulin D, is an essential molecule that helps antibodies bind to pathogens. It consists of two subunits: IgA and IgG. The term 'igDlna' refers to a specific feature in the immunoglobulin N (IgN) region that makes it more susceptible to the effects of certain toxins and infections. Definition: IgDna is an essential molecule that helps antibodies bind to pathogens. It consists of two subunits, IgA and IgG. Specifically: - IgA is the first amino acid in the IgDna region. This amino acid is crucial for the formation of IgA in the plasma membrane. - IgG is a secondary structure composed of five alpha helices (α1–α5), and it acts as an antibody receptor on the surface of the T cells. In summary, IgDna helps antibodies bind to pathogens effectively by preventing these toxins from causing severe damage.
